The Cliché Quartet

Marylynna "Mary" Sue. Her name is that for a reason, because yes, she's a HUGE Mary Sue. She looks perfect, acts perfect, is perfect...her only 'flaw' is the fact that she's clumsy in an adorable way. She has a loving best friend, 21 loving boyfriends, loving parents, and two loving siblings, AND YET SHE'S DEPRESSED BECAUSE NOBODY LIKES HER!
Let's just say, you'll be rolling your eyes straight out of your sockets, trying to make some sense out of Marylynna's logic.

Ryder Griffin is one of Marylynna's 21 boyfriends. He's extremely protective of his girl, so he doesn't let any 'heterosexual male' within five kilometres of her. And no one is safe, not even Mary's own father or brother.
You'll swoon over his stalkerish and manipulative behavior, and you'll totally fall in love with this etheral bad boy, even if you're a 150-year-old grandpa.

Chrissy Mathis is a stereotypical blonde cheerleader, probably the most popular girl in school, and Mary's archenemy. So obviously she's a slut for wearing lip gloss, and a bed-warmer for having a boyfriend, because as you can see, Mary's logic is utter trash.
You'll quickly find her awesome, because she's the ONLY female character with more than one personality trait.

Luck Harris is the stereotypical loser. Few friends, loner. He wears braces and has really suckful grades. Everyone compares him to his older brother, Wiliam (another one of Mary's boyfriends), and he hates it.
You'll be rooting for him in his quest to win Chrissy's heart because then again, he's the ONLY male character with more than a single personality trait.
